1- claim. r(cruz-141)' This invention 4relateirto beverage cooling and dispensing apparatus, and particularly to such'an apparatus wherein one'or morelsyrups and a carbonated water have a common cooling meansy and are selectively dispensed. L

The object of thefinvention -is the provisin of an apparatus of this character `comprising a casing, a 'compressor, a condenser and an evaporator, and having anovel arrangement of such parts whereby space is conserved and cooling is effected in an eilicient an'd economical manner.

Other objects and advantages of the invention will be apparent from the following detailed deconduction and convection.

provided between the tank- I8 and the wall of the scription, and from the accompanying drawings showing one embodiment thereof, in` which- Fig. 1 is a central verticalsection of a dispensing apparatus embodying the invention with parts in full and parts broken away; Fig. 2 is a partial horizontal cross-section thereof,on the line 2-2 in Fig. 1; Fig. 3 is a central vertical section kof the annular carbonated water tank and associated cooling coil, and Figs. 4 and 5 are top plan and side views, respectively, of a different .form of tank and cooling coily arrangement for the carbonated water. Referring to the drawings, I0 designates a cooling shell or structure forming a cooling charnber l I with heat insulated walls, such chamber, in the .present instance, being of circular form in cross-section. The top'wall of this chamber is lprovided with a centrally disposed opening I2 that is closed by a removable, cover I3. A liner I4 of a suitable heat insulating ncn-hygroscopic material is provided in the wall of such opening and forms, at its top, a seat for the cover and at its lower edge an inwardly projecting annular hook or shoulden I5.

' One or more cans I6 are suspended through the opening I2. down into the chamber I I and for such purpose eachis provided at its top edge with an outwardly turned flange I1 for engaging over the A narrow space is chamber il and in this is disposed a cooling coil I9 of the refrigerating system employed.

The shell I0 is ysuplzported by a casing structure 2Iwith the front end of the shell projecting forwardl in overhanging relation to the casing. In

the bottom portion of the casing beneath the shell is mounted the compressor 22 of the refrigerator system, to which one end of the coil I8 is connected, and at the rear of'this and extending upV yatthe rear side of the shell III is the condenser 23 to which the otherend of the coil III is connected. This condenser is of the static type and preferablyinclined to allow eicient` cooling. In order to support the shell I0 and also house the compressor 22 and condenser 23, the casing 2| is of substantially L- form in vertical section with the shell seating in the angle. Air enters the casing through a bottom opening 24 and discharges through a grill 25 at its upper end.

carbonated water is supplied to the tank I8 through one or the other of' two tap' holes 21 (Fig. 3) in the'tank bottom and one or both of these, if desired, may have communication with the interior top portion of the tank through an extension pipe 28. The other ofsuch holes has connection with a discharge pipe'29 leading to an outlet passage 30 (Fig. 1) in ajvalvel body 3l. This body is secured in and projects downwardly from an opening in the bottom oi' the shell III,

hooked edge I5 of the liner I4. If a-single can is l used, it is round in cross-section. It is preferable, however, to provide two or more cans of sectorshape, which together flt down through the liner opening into the chamber andcombine to 4form a cross-sectionally round unit. In the present inare used, as shown in Fig. 2. o

-Mounted within the chamber II around the can-or cans I6 is an annular tank I8 for containing carbonated water,1the inner wall `of this tank being disposed in adjacent relation to the outer circular or arcuate walls of the cans I6 whereby one may be cooled from the other by and in the present instance has two outlet passages (not shown) in connection with respective,

outlets in the bottoms of the two syrup cans I6. The valve is equipped with a. rotatable member 34 controlled by a handle 35 and having a single discharge orifice 36 with one or more passages 31 leading thereto and adapted to be selectively placed in register with the passages 30, and other passages (not shown) in the valve body, or all 'may be closed thereto by predetermined movements ofthe member 34, as well understood in the art.-

limited to any speciiic construction, arrangement or form of the parts, as it is capable of numerous modifications and. changes without de parting from the spirit of the claim.

Having thus described my invention, what ll claim as new, and desire to secure by United States Letters Patent, is:

In a liquid coolingl apparatus, a refrigerating system of the type, incldinga compressor, a coridenser and an evaporator; a hollow casing substantially L-shaped in vertical section defining a chamber and a shelf like seat, one portion of the chamber being of greater vertical dimension than the remainder of the chamber, and the cross-sectional area of the said one portion oi the chamber taken on a horizontal plane being of lesser dimension than the cross-sectional area of the remainder of the chamber, said compressor and condenser being positioned in the hollow casing, the condenser being located mainly within said one portion of the chamber and the compressor bein-g located mainly within the re-v mainder of the chamber; an insulated shell formlshelf like seat of the casing, said insulated shell having a portion extending outwardly from and in overhanging relation to said remainder of the chamber, said insulated shell containing the evaporator of the refrigerating system,
